I had v3, but it should have similar logic and also got ack from Rob
I knew all your logic of adding binding document for all MediaTek devices, even I alway added MediaTek device in dt-bindings as the way you mentioned here, but I felt this way is fine for this kind of dedicated document.
The reason i don't add it as usual is the following. 8250.txt is common and shared among all uart like devices, so i don't want btif device occupies too much section and bloat the document when every new MediaTek SoC is introduced.
So instead I refer to existing Nvidia device added in 8250.txt which I thought its way is simple, elegant and also using pattern I can use to add btif devices.
